Enertex® KNX LED Dimmsequenzer 20A/5x in variants for ceiling mount (DK) and DIN rail (4 SU)

The Enertex® KNX LED dimming sequencer 20A/5x is a pulse width modulating 5-channel dimmer for 5 - 48 V LED modules. Per channel the dimmer can dim up to 20 A LED current and in total 480 W power maximum.

The dimmer is suitable for any LED lighting device that are suitable for DC constant voltage. Since the overcurrent switch-off of the dimming sequencer has been designed to be very robust against false triggering at high inrush currents, it is also particularly suitable for lamps that have very high inrush currents.

We recommend the Enertex® LED PowerSupply 160 series to supply the lamps.

With the help of the display and the push buttons the installation of the complete lighting can be tested and put into operation without ETS software. The different dimming curves, PWM frequencies and dimming speeds for the connected lamps can also be tested via the menu on the display. The choice of four predefined dimming curves in conjunction with a dimming frequency between 211 Hz and 1200 Hz means that a suitable configuration for smooth and flicker-free dimming can be found for almost all lamp types.

The device has a reverse polarity protection, overvoltage and undervoltage protection, overtemperature protection and overcurrent protection, which acts selectively. During operation, the device measures the actual currents and powers in each channel, the DC input voltage, the device temperature and the telegram rate. To record the power costs for the lighting, the device provides energy and cost counters for each channel by means of communication objects.

The independent channels can be parameterized in the application in any combination of cool white / warm white, as color channels or as individual channels. Current RGBCCT lighting stripes (red, green, blue, cool white, warm white) are also optimally supported. These lamps are perfectly staged with an automatic white balance (RGB-Extended) developed by Enertex or with the extended Tunable White color temperatures, which are generated by automatic admixture of R/G/B (TW-Extended).

The colors can be controlled either via the primary colors red, green and blue (color mode RGB) or via hue, saturation and brightness (color mode HSV). The dimmer supports 8-, as well as 1-bit scenes and also enables the locking of individual channels / channel groups by means of communication objects. Five sequences, i.e. sequences of color or color temperature controls in the range from seconds to hours with smooth color changes, can either be defined by the user or assigned to over 20 predefined color sequences. Different switch-on behaviors for day and night are supported as well as time-controlled dimming of channels / channel groups. The latter enables, among other things, time-of-day-dependent white light control (Human Centric Lighting / HCL) in Tunable White mode. The setpoints can be specified either as absolute times or relative to sunrise or sunset (astro function).

The bus communication can optionally be encrypted by means of KNX Data Secure.
